Abstract
The present disclosure discloses a signal transmission method and device, a terminal and an access network device. The method is applied to a first access network device and includes: obtaining first position information of a second access network device and obtaining second position information of a target terminal; and determining a precoding coefficient for performing precoding processing on data sent to the target terminal according to the first position information and the second position information.
Claims10
A signal transmission method, performed by a first access network device, comprising:
- obtaining first position information of a second access network device and obtaining second position information of a target terminal;
- determining a precoding coefficient for performing precoding processing on data sent to the target terminal according to the first position information and the second position information;
- sending the precoding coefficient to the second access network device;
- wherein the first access network device and the second access network device are different access network devices.
A signal transmission method, performed by a second access network device, comprising:
- determining a precoding coefficient for performing precoding processing on data sent to a target terminal;
- wherein, the precoding coefficient is received from a first access network device after the first access network device determines the precoding coefficient according to first position information of the second access network device and second position information of the target terminal;
- performing precoding processing on the data sent to the target terminal according to the precoding coefficient;
- wherein the first access network device and the second access network device are different access network devices.
